【推荐1】On Dec. 28, a small satellite (卫星) was launched (发射) into space from Taiyuan, Shanxi. It was big news for students at Beijing Bayi School. After all, they designed the satellite.
With the help of space scientists, more than 30 students built this satellite (12cm long, 11cm wide and 27cm tall). This is the first satellite designed and built by middle school students in China.
This August, the school worked with the China Center for Aerospace Science and Technology International Communications and started the satellite program. It allowed space experts to teach students about basic knowledge of satellites.
After several months of hard work, students designed their own satellite. Their main achievement was the design of the satellite’s functions in space. “We worked together and came up with more than 10 ideas. But after tests and experiments, we settled on four,” Zhu Xun, 16, told Beijing Evening News.
Indeed, they have to consider the weight of the satellite. The satellite will stay in space more than 180 days. Its functions include taking pictures of Earth, radio communication and sending information to Earth. The students hope that the satellite can take photos of smog, typhoons (台风) and other weather conditions.
The students were divided into five groups. The group members worked closely to make satellite models. “Every time we think the satellite we are designing will fly into space, we are so excited and try to do experiments,” said Shen Shulang, 17. They also visited the Chinese Academy of Sciences and other organizations to get inspiration (灵感).

Over a million people around the world lose their lives in car accidents each year. While nearly all of these deaths are the consequence of human mistakes, there are no good ways to reduce（减少）the number of deaths. Surely the best plan is driverless technology.
Driverless cars are no longer an idea of the future. With the technology for the driverless car already developed for quite a long time, and some important inventions already seen in some cars, the driverless car could soon be with us.
This is wonderful because driverless technology is expected to reduce the number of road deaths. A research group in the United Kingdom says that driverless cars will lead to 2,500 fewer road deaths before 2030.
How are driverless cars safer? Firstly, driverless cars can help manage traffic. By using communication technologies to “talk” to each other, driverless cars find the best roads. Information such as distance（距离）between cars, traffic and time it takes to get to the place is sent to the cars. This means fewer possibilities of these cars running into each other. Secondly,the use of driverless cars means fewer accidents will happen because of human mistakes. For example, accidents caused by little sleep, drunk driving or speeding will be avoided. Finally, the driverless technology of the future, is expected to be more reliable（可靠的）than a human driver.
If lives can be saved by driverless cars, let’s hope these cars are on our roads very soon.

【推荐3】The Palace Museum, one of the greatest ancient wonders of China, is using modern technology.
Back in December 2015, a digital gallery (数字馆) at Duanmen opened in the Palace Museum. A film on the screen helps visitors learn about the museum in a short time. Then visitors can walk into a palace, seeing and touching many treasures through VR. They can even talk with ancient people with the help of AI.
In fact, digitalization of the museum started 20 years ago. In 2001, the museum first opened websites in Chinese and English. Visitors from all over the world can see the introduction and new notices online. In February 2015, the museum offered an app (应用软件) to show its collection. The app introduces one treasure every day. In 2018, the museum developed a program on WeChat. The program advises visitors on the best visiting way through the museum.
During the outbreak of the COVID-19 virus, the Palace Museum also turned to the Internet. As a result, on April 5 and 6, it provided three live-streamed (直播的) tours. The three tours took different ways around the Palace Museum. Two researchers from the museum became tour guides, telling people stories about the place.
What’s more, the Palace Museum has worked with Huawei to build a smart network of 5G throughout the museum. Huawei will also use AI to help with the protection of art works.

【推荐2】Six hours of walking in space! On August 20, Chinese astronauts Liu Boming and Nie Haisheng did the second spacewalk of the Shenzhou XII task. They set up some equipment (设备) and lifted a camera outside the Tiangong space station.
Spacewalks can be dangerous. There is no air in space, of course. And it’s filled with harmful radiation (辐射). But the spacesuits, although they look wider and bigger, can protect astronauts.
A spacesuit is like a small space station. It has everything astronauts need when they carry out a spacewalk. For example, China’s Feitian spacesuits have six layers. The innermost layer (最内层) collects astronauts’ urine (尿液). Then there are four layers that help control the temperature and air pressure inside the suit. Spacesuits are filled with air, so they look like they’re puffed up. The sixth layer is made of special materials that protect astronauts from radiation.
Astronauts can walk freely because they are connected to the space station with safety ropes. The suit has headphones and speakers for astronauts to communicate. There is also a mirror on the arm. Astronauts can check their suits by looking at it.
The first Feitian suit was made in 2008. Zhai Zhigang wore it to carry out China’s first spacewalk for about 19 minutes. The suits Chinese astronauts wear today are the second generation (代) of Feitian. It can support walks as long as eight hours and can be used more often. The first generation could only be used more than five times within two years while the second generation can be used 15 times within three years. Each suit costs around 30 million yuan and it takes four months to make just one!

【推荐3】Height (身高) is just one of the thousands of features (特征) that your genes (基因) decide. In fact, because you have two parents, your genes provide you a height that usually lands somewhere between the height of each parent. If both your parents are tall, then maybe you will be tall, too, but if you have questions about how tall you’re going to be, ask your doctor if he or she can help you find it out.
But genes don’t decide everything. For example, eating an unhealthy diet can keep you from growing to your full potential(潜力). Getting enough sleep and enough exercise will help you grow to the right height.
Maybe you’re wondering how fast you should grow. There’s no right answer. Kids grow about 2 inches(5 centimeters) a year between age 3 and the time they start puberty.
Your doctor will know how your growth (生长) has been going over the years. Two centimeters here and 2 inches there are not nearly as important as the height you’re at now, how you’ve been growing up to this point, and what other changes your body may be going through.
Don’t be worried if you have grown a lot in a very short time. Everyone has a very quick growth during puberty. The age for starting puberty is about 10 for girls and about 11 for boys. But it can be earlier or later—between 7 and 13 for girls, 9 and 15 for boys.
You usually begin to find that you’re growing faster about a year after your body starts to show the first changes of puberty.

【推荐1】Last month we asked our students about their free time activities. Our questions were about exercise, use of the Internet and watching TV. Here are the results.
We found that only fifteen percent of our students exercise every day. Forty-five percent exercise four to six times a week. Twenty percent exercise only one to three times a week. And twenty percent do not exercise at all.
We all know that many students often go online, but we were surprised that ninety percent of them use the Internet every day. The other ten percent use it at least three or four times a week. Most students use it for fun and not for homework.
The answer to our questions about watching television were also interesting. Only two percent of the students watch TV one to three times a week. Thirteen percent watch TV four to six times a week. And eighty-five percent watch TV every day! Although many students like to watch sports, game shows are the most popular.
It is good to relax by using the Internet or watching game shows, but we think the best way to relax is through exercise. It is healthy for the mind and the body. Exercise such as playing sports is fun, and you can spend time with your friends and family as you play together. And remember, “old habits die hard”. So start exercising before it’s too late!
